Ok, i had this problem with VC++ 6.0 out of nowhere about a week ago, at which time it was installed on my d:\ drive(hard disk).
So i uninstalled and reinstalled on my c:\ drive and its STILL doing it.
It says for any and every program when u try and compile:
And thats ALL it says, WTH?!?!--------------------Configuration: hello - Win32 Debug--------------------
Compiling...
Error spawning cl.exe
hello.obj - 1 error(s), 0 warning(s)
